I am getting a 1/2 inch brown mark on the page .when I removed the yellow drum it also had the mark on it like the cleaning blade was not working. have anyone seen this before. all of the other drums are not doing it.

That would seem to indicate the yellow drum unit was bad, so surely you've tried changing it. Therefore it must be something else, so we need more input, please.

If its brown its most likely a problem with the transfer belt cleaning assy. Check the cleaning blade and replace if needed.
